find-skill skillA
find-skill is agent-read markdown (skill) from wangchangxin0809/cc-repo-harness: Find a Claude Code skill or plugin somebody else has already written, and judge whether to install it. Use before writing a skill for something that sounds common, when asked whether an integration exists, when looking for a plugin by capability rather than name, or before adding a skill that would duplicate one installed..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Finding somebody else's skill
The cheapest skill is the one you did not write. There are 291 plugins in the
official marketplace alone, already on this machine, and the question "does this
exist" is answerable in one grep before it is answerable in an afternoon.
- **Covers**: where to look, in which order, and how to decide.
- **Does not cover**: writing one — that is `writing-checks` for anything that
can pass or fail, and `writing-docs` for anything that explains.
## Look here first, because it is local and exact
Every configured marketplace is already cloned. Its manifest is one JSON file
with a name, a description, an author and a category per plugin, so this is a
grep and not a network call:
```bash
claude plugin marketplace list # which ones this machine has
```
```bash
python3 - <<'PY'
import glob, json
for m in glob.glob("~/.claude/plugins/marketplaces/*/.claude-plugin/marketplace.json"):
for p in json.load(open(m))["plugins"]:
blob = f"{p['name']} {p.get('description', '')}".lower()
if "YOUR TERM" in blob:
print(f"{p['name']:<34} {p.get('description', '')[:80]}")
PY
```

How to install
mdr add wangchangxin0809/cc-repo-harness/find-skill@git:20260903.c1a383cmdr add wangchangxin0809/cc-repo-harness/find-skill@sha256:b7e50bd97d9b50c2Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
